The Australian and South Australian governments are providing the last and most complicated section of the North-South Corridor.
The 10.5km T2D Project is the most impressive infrastructure project ever undertaken in South Australia. It will complete the North-South Corridor, delivering 78km of non-stop motorway between Gawler and Old Noarlunga.
It will stimulate economic growth while sustaining livability, unlock Adelaide’s traffic network, and provide long-term benefits for South Australians. In addition, it will assure people, produce, and products arrive where they need to be sooner and safer, assisting in lowering costs for businesses and enhancing services for customers by providing:
- decreased travel times to key destinations, containing the CBD and main gateways such as Port Adelaide and Adelaide Airport;
- a vital route for heavy vehicles and commercial freight trips; and
- a continuous road connection linking Gawler in the north and Old Noarlunga in the south.
The T2D Project will provide two sets of twin three-lane tunnels, lowered and ground-level motorways, and overpasses and underpasses at critical intersections.
Once completed, over 50 per cent of the T2D Project will be motorway tunnels. Moreover, the T2D Project will link communities across Greater Adelaide by moving thousands of vehicles into underground tunnels and bypassing 21 traffic light sets.
The southern and northern sections of the T2D Project will comprise parallel tunnels with three lanes in each direction. The Southern Tunnels will run from Clovelly Park to Glandore; and the Northern Tunnels will run from Richmond to West Hindmarsh.
Major construction on the T2D Project is anticipated to start in 2025.
The first TBM to be used to construct the Southern Tunnels is organized to begin tunnelling in 2026.
It is worth mentioning that the project completion is expected to be in 2031.

South Australian firms can register their interest in being involved in the River Torrens to Darlington Project via the project page on the Industry Capability Network (ICN) Gateway website portal.
